Phenotypic evaluation of DH-lines developed on the base of rice samples with blast resistance genes

Gametoclonal changes are an additional source of genetic variation suitable for use in crop improvement programs a range agronomic traits. The aim the study was to accelerate development genetically stable DH rice lines with high morphological and uniformity by method experimental haploidy vitro based on breeding valuable samples specified characteristics carrying genes wide spectrum blast resistance, as well racespecific resistance pathogen, subsequent assessment traits androgenic lines. data callusogenic regenerative capacity 30 genotypes domestic Chinese introduction anther culture presented. Genetically (homozygous) were developed basis these samples. economic biological elements panicle productivity DH-line from three given. variability arising result gametoclonal noted such plant height, length, weight 1000 grains.
